SIX NEW SPECIES OF FRANKLINIELLA AND A KEY TO THE
AMERICAN SPECIES.!
‘BY A, C. MORGAN,
Bureau of Entomology, U. S. Dept. of Agriculture.

The addition of six new species to this our largest genus of American
Thysanoptera justifies, I think, the inclusion of a key for the separations of
the twenty-four species and five varieties here recognized.

For the form tritici described by Moulton (Tech. Ser. No. 21, Bur. Ent
U. S. Dept. Agr., 1911) under the varietal name, californicus, | agree with Mr
J. D. Hood? that the name was preempted by E. ulicis californicus and have
restored the name moultoni as suggested by Mr. Hood (loc. cit.).

The description of F. cephalica Crawford and F. melanommatus Williams
suggest the same species in most respects but it seems to me that the differences
pointed out by Mr. Williams® certainly entitle melanommatus to varietal rank,
at least, and I have so ranked it in this paper. Also the fact that cephalica was
collected in the mainland and melanommatus on an island strengthens us in the
conclusion that the differences of the two forms are very probably constant

Head about 11%4 times as broad as long, broadest at the middle, very
slightly arcuate in front; eyes occupy a little more than half the width of the
head and a very little less than half the length, rather finely facetted; ocelli
very large—much larger than the facets of compound eye—widely separated,
although the large, deep orange crescents that border them inwardly are approx-
imate at their inner margins; behind the eyes rather coarsely and deeply trans-
versely striate—one of the striae more prominent than the others. Interocellar
and postocular bristles prominent; the interoculars situated well inside an
imaginary line connecting the centers of posterior and anterior ocelli. Cheeks
convex, slightly roughened with one short distinct spine, anteriorly directed just
back of middle. Mouth cone evenly cone-shaped and extending about 34 across
prosternum. A row of six tiny spines may be seen between postocular bristles.
Antennae with third segment bearing a pseudo joint at the base, and stalked,
four joined to three rather broadly and four and five are thicker at base than

cones on 3 and 4 and a long slender simple cone on inner side of 6.

Prothorax fully 114 times as broad as long, broadest at middle, posterior
angles broadly rounded, spines at the angles prominent and dark brown, poster-
ior and anterior marginals equal in size but only about 4 as large as those at
the angles; the usual row of small spines is present on the posterior margin,
also a row of about 8 tiny spines on anterior margin between spines at angles.
In addition to the large spine on anterior angle there is also a much smaller
and shorter anteriorly directed spine. Surface rugulose with weak transverse
Striae near posterior margin. Mesothorax broad with spines as in F. insularis.
Wings reach to middle of 8th. abdominal segment (specimen somewhat distended),
broadest at the base, at the middle 1/11 as broad as long, basal fifth gray, re-
mainder of wings distinctly darker, gray brown; costa bears about 24 to 26
spines, anterior vein 19 to 20, posterior vein 14 to 17. Legs of moderate
size, the usual spines strong and the surface of all pairs clothed with numerous
small spines.

much longer spine than either of the two preceding ; on the posterior margin two
very stout spines are to be found each side the meson, one on each side the sec-
ond spine of the preceding three and about half-way between it and the spine
at meson and lateral angle respectively; of these two spines the outer one is
not more than 1/3 as long as the one at the posterior angle and the one near
the meson not more than 1/3 as long as the outer, but much stouter. Each
lateral posterior margin of the 1oth. segment bears a heavy incurved spine slight-
ly longer than the one at the lateral angle of the gth. segment. Length of

Described from 1 male taken in company with the Holotype.

This well marked species is very closely related to F. insularis, Franklin,
from which it may be easily distinguished by the greater comparative differences
in the lengths of the 7th. and 8th. antennal segments and by the position of the
interocellar bristles. In F. insularis these bristles would touch the line tangent
to the outer margins of the anterior and posterior ocelli. In australis these
bristles stand inside the line from center to center of anterior and posterior
ocelli. The coloration of the antennae is distinctive as is also the heavier con
struction of the fourth segment basally.

Frankliniella gilmorei new species.
Female: color by reflected light; abdomen, legs, head, and first five—and
base of 6—antennal segments very light lemon, thorax light lemon, eyes dark red,

distal antennal segments fuscous, mouth cone tipped with black, wings practically
transparent, the head washed with lemon in front. By transmitted light the whole
insect is pale yellowish, deeper in thorax, eyes black, tip of mouth cone black,
distal antennal segments—outer half of six and seven and eight—light brown to
fuscous. :

Head fully 114 times as broad as long, slightly arcuate in front between
eyes, only very slightly produced between antennae, cheeks slightly swollen, con-
vex, and bearing a few tiny colorless spines; eyes occupy nearly 3/5 the width
of head through them and about % the length, facets of moderate size, slightty
pilose; ocelli situated far back, large, the posterior ones in line with posterior
margins of compound eyes, margined inwardly with large orange crescents. In-
terocellar bristles well developed, brown, postoculars weak. Mouth cone long,
reaching across prosternum, pointed, its sides concave in outline, tipped. with
black. Antennae about 2% times as long as head, the segments comparatively
broad and heavy.

Prothorax about 114 times as broad as long. All of the usual spines
present, sides only slightly convex, mesothorax about % broader than prothorax,
wings at middle 1/11 as broad as long, reaching to 8th. abdominal segment, costa

Described from 8 females collected from a species of mint, Clarksville,
Tenn., May 20, 1915. Named for the collector, Mr. J. U. Gilmore. No males
found.

This little species may be easily distinguished from its nearest relative,
F. runneri, Morgan, by the different shape and size of the mouth cone. In F.
runneri the mouth cone has straight ‘sides and reaches only about 2/3 across the
prosternum, while iin the present species it extends clear across the prosternum,
is pointed and the lateral margins are distinctly concaved.

NEW MICROLEPIDOPTERA FROM THE SOUTHWEST
BY ANNETTE F. BRAUN,
Cincinnati, Ohio.
Lithocolletis manzanita n. sp.

Palpi white, blackish outwardly ; antennae gray, with narrow paler annul-
ations ; head white, the tuft with a few fuscous hairs. Thorax brownish ocher-
ous, with a white anterior transverse band passing on each side obliquely across
the ends of the tegulae. Fore wings golden brownish ocherous; a broad median
silvery white basal streak, broadening to the fold in a blunt angle on its under
side, and margined all around with black scales; a short broad dorso-basal white
streak, also black-margined, joins the median streak at base. Five costal and
four dorsal silvery white spots. First costal spot, before the middle, quadrate,
black-margined on both sides, its apex before that of the first dorsal. First dor-
sal quadrate, black-margined on both sides, its inner edge angled just below
the apex of the median basal streak, its black margin produced along the middle
of the wing and touching the apices of the broadly triangular second dorsal spot
before the tornus and the narrower third dorsal spot beyond the tornus. A fourth
dorsal spot just before apex is confluent with the third on the margin. \ Apices
of second and third costal spots opposite apices of the corresponding dorsal spots.
Apices of fourth and fifth costal and fourth dorsal spots meeting. A few
black scales on outer side of fifth costal spot at apex. Cilia white. Hind wings
pale silvery gray, with ocherous-tinged cilia. Legs white, fore and middle pair
shaded with blackish fuscous, posterior tarsal segments black-tipped above. Ex-
panse: II mm.

Type (2) reared from a miner of manzanita, Arctostaphylos manzanita,
Mt. Wilson, California. Mine found March 6, at which time the larva was full-
grown; imago, March 30.

The mine is a gray:sh blotch, with the upper epidermis loosened and elevat-
ed, but at no stage wrinkled, producing a somewhat inflated mine in which most
of the parenchyma is consumed. The larva belongs to the cyfindrical group.

Lithocolletis inusitatella n. sp.

Palpi pale golden ; antennae with alternate annulations of whitish ocherous
and fuscous; face pale golden; tuft brownish ocherous. Thorax and ground color
of the fore wings lustrous golden; upon this ground color the position of faintly
paler costal streaks and scarcely discernible dorsal streaks is marked by the
darker more brownish shades which form their inner margins. A faintly paler
shade begins on costa at base, broadening outwardly and is margined beneath
by a faint brownish line which extends along the middle of the wing and joins in
succession the very oblique inner margins of two faint pale golden costal streaks,
the first starting at the middle of costa. There is thus along the middle of the

wing a more brownish golden shade. The third and fourth costal streaks are
narrow, inwardly oblique, more nearly white, and opposite two similar streaks
above the tornus, of which the first is often absent. Opposite the first oblique
costal streak, a faintly paler shade sometimes indicates the position of a dorsal
streak ; just before tornus a darker shade marks the inner margin of a second
dorsal streak. A small black apical spot. Scales at margin around apex bluish
metallic. Opposite the apical spot, a brown pencil of scales projects the length
of the cilia*beyond them. Hind wings gray, with ocherous-tinged cilia. Legs
silvery. Abdomen fuscous above, silvery beneath. Expanse: 8-11 mm.

Type (4), and five paratypes (3¢, 29), reared from large underside
mines on oak, Quercus agrifolia, Mt. Wilson, California. Mines collected March
6, when the larvae had pupated; imagoes April 2 to April 13; the date of emer-
gence of the type April 4.

The mine is 2 to 3 cm. long, I to 1.5 cm. wide, with two or three widely
separated wrinkles at maturity; leaf little bent. Cocoon a loose meshwork at-
tached to the upper epidermis.

Lithocolletis cretaceella n. sp.

Palpi, face and tuft white, sides of the tuft ocherous. Antennae white,
with fuscous annulations; two broad widely separated rings near the tip. Thorax
white, with a median transverse ocherous and black band. Fore wings white;
a golden ocherous band, with a patch of black scales on costa and dorsum, crosses
extreme base of wings; three curved ocherous streaks nearly reaching costa, near
base, before middle, and beyond middle of dorsum, each margined inwardly by a
line of black scales; the second and third of these are angulate near costa, the
short arm of the third produced as a broad ocherous bar to costa. The apex of
a narrow dorsal streak at tornus joins a patch of black dusting below apex
Marginal line of scales around apex ocherous; a single line of black scales begins
on costa before apex and joins the patch of dusting. Cilia white; a tuft of
ocherous scales opposite apex. Hind wings and cilia silvery, faintly ocherous.
Legs white, with black and fuscous transverse and oblique bars; tarsi black-
tipped. Abdomen white; paired brownish oblique streaks on the underside; four
longitudinal streaks along the last three segments. Expanse: 10.5 mm.

Type (2) reared from a blotch mine on the upper side of a leaf of oak,
Quercus hypoleuca, White House Canyon, Santa Rita Mountains, Arizona.

The mine, found March 17, is a yellowish and brownish blotch, with a
single wrinkle in the epidermis; the imago emerged April 12.

Although the general type of marking is that of L. macrocarpella, this
species is very different from all other described species of the flat-larval group
in the preponderance of white on the wings.

Lithocolletis arizonella n. sp.

Palpi and face white; tuft white, hairs on each side and in the middle
reddish ocherous. Antennae white beneath, dotted with black above; darker
toward tip. Thorax and fore wings reddish ocherous; two broad white stripes
on the thorax ; each stripe continuous with a white stripe which crosses from tie
base of the wing to the dorsal margin beyond the basal angle, thus leaving at
the basal angle a small elongate spot of ground color. The dorso-basal white

stripe extends to the middle of the dorsum, whence it is deflected upward as a
very oblique narrow white streak which meets at an acute angle a narrow oblique
white costal streak; the angulated fascia thus formed is heavily black-margined
before and at its angle. Before this fascia an oblique white costal streak, with
black scales at its tip. A small spot on costa beyond the fascia, and beyond this
an oblique white streak which meets in a V an inwardly oblique white streak
preceding the dusted patch at the apex. An oblique outwardly black-margined
streak at tornus. Cilia ocherous. Legs white, with reddish ocherous bars, tarsi
black-tipped. Expanse: 8.5-9 m..

Type (¢) and four paratypes (24, 22) reared from upper-side mines
on Arbutus arizonica, White House Canyon, Santa Rita Mountains, Arizona.

The mine is a broad tract, with loosened epidermis at first somewhat green-
ish, later brown. The larva pupates toward one end of the mine, where the
epidermis is thrown into two short folds. The epidermis around the margins of
an oval area, in which the pupa lies, is somewhat puckered. Mined leaves collect-
ed March 17; imagoes April 9 to April 22.

This species is separated from its allies of the conglomeratella group by
the two white stripes of the thorax and the patch of ocherous ground color at
the basal angle of the fore wing.

Acrocercops arbutella n. sp.

Labial and maxillary palpi white, second segment of each fuscous out-
wardly at base; antennae brownish ocherous; head white. Thorax white, tegulae
ocherous. Fore wings shaded golden brownish ocherous, the deeper shades pre-
ceding the white spots. Three large, nearly half-oval white spots on the dorsal
margin, the first narrowly extended to base, and an elongate white spot beyond the
tornus. Costa before middle whitish, shading into the ground color below the
margin; beyond middle, a curved white costal streak, its apex opposite the space
between the second and third white dorsal spots, followed by a white streak not
clearly defined. Beyond this a straight narrow white band passes obliquely across
the wing, and parallel to it a straight broader band, both running into the white
elongate spot beyond tornus. These two parallel white bands are cut by two par-
allel longitudinal fine black lines in the middle of the wing, the lower one mar-
gining the upper edge of the elongate white spot. Before the lower line, and in
a line with it, is a shorter less distinct blackish or dark brown line. A triangu-
lar white streak crosses the ocherous costal cilia to the extreme apex of the wing;
at the apex of the wing is a group of brown or black scales. A white band crosses
the cilia at apex. Outer half of cilia below apex white. Hind wings pale gray,
cilia ocherous in the basal half. Legs white, segments shaded with ocherous and
tipped with black. Expanse: 11-12.5 mm.

Type ( 4 ) and twenty-two paratypes ( ¢ and @ ) reared from large upper-
side blotch mines on leaves of Arbutus arizonica, White House Canyon, Santa
Rita Mountains, Arizona.

The loosened epidermis of the mine is very thin, whitish at first, later
brownish; the parenchyma is either almost entirely consumed over about half
the mine, or irregularly eaten over the whole mine. Cocoon broadly oval, reddish
ocherous. Mines collected March 17; imagoes April 11 to April 18. ;

Leucoptera robiniella n. sp.

Head smooth, shining silvery white, thorax and fore wings shining white.

Beyond middle of costa, an oblique yellowish bar, edged on both sides with dark
' fuscous, followed by a second perpendicular bar, also fuscous-edged; both of
these bars terminate in a median longitudinal reddish coppery patch before apex
Below the second bar a large violet metallic patch beyond tornus, preceded and
followed by large patches of black scales. Three diverging black lines in the apical
cilia. Hind wings gray. Expanse: 5-6 mm.

Type (¢) and five paratypes (34,29), reared from miners of leaves
of Robinia neo-mexicana, Bright Angel Point, North Rim, Grand Canyon,
Arizona, 8100 feet altitude.

The mine is a greenish, slightly irregular blotch, on the upper side of a
leaflet ; it begins as a very narrow linear mine abruptly enlarging into the blotch,
which usually obliterates the linear mine. Cocoon of the usual Leucoptera type;
in this case the flat silken bands are not as regular or as evenly spun as usual,
and one is broader than the other, which is often merely a few strands of silk
These bands are not joined across to one another but each is joined to the inner
cocoon by an inwardly sloping narrow band.

The larvae were collected July 26 and pupated soon after; imagoes
April 3 to April 4.

NEW TACHINIDAE IN THE CANADIAN NATIONAL COLLECTION
(DIPTERA)*
BY C. H. CURRAN,
Ottawa, Ont.

Most of the species described in the following pages belong to Hypostena
as used by Coquillett in his revision of North American Tachinidae. While Town-
send has established a number of genera, it is difficult to follow him, and the
material before me indicates that these genera are too weakly differentiated to
be recognized, I have therefore used the name Hypostena, even though Coquillett
later considered that Tachinophyto should more properly be used for our North
American species.

Hypostena (Arrhinomyia) ouelleti new species.

Allied to H. barbata but differs in the length and strength of the frontal
bristles, bristly facial ridges on lower half, narrower front, more slender form,
etc.

Length, 5 mm. Male.—Head silvery white pollinose, the upper fourth
of the front with brownish yellow pollen, one long slender bristle among the long
hairs on the cheeks. Vibrissae on level with oral margin. Facial ridges with
bristles of almost equal length on lower half to three-fifths; face on lower por
tion about as wide as eye, with low median carina on whole length. Front
hardly one-fifth head width, the frertal bristles long but not strong, not strength-
ened above but of almost equal length, the upper two (sometimes a weak bristle

BUCKELLIA, A NEW GENUS OF ASILIDAE (DIPTERA).*
BY C. HOWARD CURRAN,
Ottawa, Ont.

This genus is proposed for the reception of Cophura albosetosa Hine,
(eyrtopogona Cole). The genus Cophura has been used as a repository for all
species having a curved spur at the tip of the anterior tibiae which do not fit
into any other genus.

Cophura (Genotype, sodales O. S.) must be limited to those species which ,
have the face practically flat, strong bristles on the oral margin and at most
a few fine hairs on the face, abdomen flattened, with rather parallel sides.

Buckellia has the face evenly gently convex, but slightly more retreating
below and possesses a fairly strong twisted apical spur on the front tibia, the
abdomen is tapering as in Cyrtopogon and the genotype has a sericeous or grey-
ish pollinose spot on the posterior angles of the second to sixth segments. I have
a pair of B. albosetosa, in coitu, collected on Revelstoke Mountain, B. C., by Mr.
E. R. Buckell. Keel

Cophura O. S. is most closely allied to Nicocles Jaenn., while Buckellia
is related to Cyrtopogon Lw., being nearest Comantella Curran and closely re-
sembling those species of Cyrtopogon having the scutellum flattened and pollinose.
